This feature is best shown in Fig. 3. ion 58 (held in anyposition by the spring-de- The fan-casing consists of head-s 27 anda'surtent 58') is also mounted in housing 57 and rounding substantiallycircular wall 28 and is provided with a'cra'nk 59, b 'means of Ioo theabove-described annular ring 26, which which it may be turned.' As theower end of said ring is secured to the Iniddle portion of part 51 issuitably iitted tothe corresponding tube end of art 44, (see especiallyFig. 3,) I am enable by this means to vary the inclination of thestraw-delivery tube 'or chute (by manipulation of the device justdescribed) without opening the joint between said lparts 51 and 44.

The two tube-sections 51 and 52 are connected by hinge 61 in such mannerthat the 'part 52 (and the hood and other portions carried thereby) maybe folded back onto the separator for storage or transportation. Inorder that I may do this easily, I attach to the part 52 a gear-rim 62and mount upon the part 51 (in suitable bearings '63 and 64) a shaft 65,having a pinion 66, which engages with said gear-rim. Said shaft' beingprovided with crank 67, I ain enabled to operate saidpinion and gear-rimto fold the outer portion over, as will be readily understood. j

The weight of the tube or chute and its associated parts is supported bya rope 71, (see Fig. 1,) which is attached to a suitable eye. 72 thereonand passes thence back over a sheave for pulley 73 on the separator andthence down to a winding-drum 74, provided with a crank 75 andwhich issituated at a point on the lower portion of the separator-frame where itis conveniently accessible and may be easily manipulated by theoperator.

The hood at the outer end of the delivery tube or chute is shown ascomprising a neck 81, which is revolubly mounted on the end ot the tubemember 52, and several sections, as 83, 84,'and S5, which are hingedlymou n ted at 86 and are adapted to becollapsed by pulling on a suitablecord 37, but are held distended when torce is not applied to said cordbya spring 88. The outer hood-sections are reticulat'ed or perforated,as shown, so that the air will escape, permitting the straw to drop onthe stack instead of being blown violentl)r thereon bythe force of theblast. '.lhe revolving of the neck S1 (and the parts carried thereby) onthe tube part 52 is accomlplished by means of pull-ropes. 91 and 92,

Having thus iully described my said invention, what claim as new, anddesire to secure by Letters Patent, is

1. The combination, in a pneumatic strawstacker, with the delivery tubeor chute, of a horizontallydisposed fan-housing having a centralpartition in the form of an annular rim extending inwardly-from thecasing, and

a fan the blades whereof are cut away to pass astride said centralpartition, whereby a double'fan and fan-housing are embodied in a singlestructure.

.2. The combination, in a pneumatic` stranstacker, of the fan, thefan-housingl a hopper-like structure for receiving th(` straw whichdevelops into a nozzle-like eid. a delivery tube or chute hingedlyconnected'lo said nozzle-like end, a pivoted segmental rack connected tothe structure on one side of the hinge, the housing connected to thestructure on the other side of .thehinge, and a pinion mounted in saidhousing structure and engaging with said segmental rack, whereby saiddelivery tube or chute may be raised or lowered-said nozzle-like end andthe adjacent portion of the tube or chute having a segmental formationand one overlapping the other. `l

3. The combination, in a pneumatic strawstacker, with the fan andfan-housing, of a delivery tube or chute connected to said i anhousingcomposed of' two parts hingedly j connected together, one of said partshaving a curved rack pivoted on said part nl' a point. other than thehinge-pivot and the other having a shaft and pinion engaging with saidcircular rack, whereby the ont er portion of said delivery tube or chutemay be folded over in respect to the inner portion. 4

4. The combination, in a pneunnuic strawstacker, of a fan, a fan-casingtherefor extending transversely across the rear portion of theseparator, a casing into which the fancasing discharges, achaii-conveyerarranged behind said fan-casing and adapted to convey the chaii' towardthe sides, and inelosures leading said cha-ti around the fan-casing fromsaid conveyer to the casing into which the fan-casing discharges.

5. rIhe combination, in a pneumatic strawstacker, of the fan, theian-casing, a hopper developing into a nozzle-like end, said nozzle-like-end being composed of' sections one revoluble in respect to the other,and a trunk or chute composedroi' sections hingedly connected togetherand to the nozzle one hinge being provided for purpose ot'verticaladjustment and the other hinge being provided for purposes of foldingthe outer portion of the chute overfor storage or transportation,l

and means for effecting said hinge movements separately.

6. The combination, in a pneumatic strawstacker, of a fan, a casingtherefor having a lower portion. axially extended beyond the ends of thefan, and a chad-chute leading into said extended portion,

7. 'Ihe combination, in a pneumatic stra stacker, of a fan, a casingthereforv having a lower portion extending beyond the ends of the ianstructure and surrounding thceyes of the fan, and a chad-chute leadinginto the extended portions of the tan-casing structure.

8. The eombin ation, in a pneumatic strawstackcr, of a fan havingtubular fan-eyes, a casing surrounding said fan ci a greater lOO IlO
